connecting to presto (ssl Enabled) using keystore.jks via Azure Databricks cluster RRS feed

  • Question

  • Hi I'm Trying to connect to presto database (ssl Enabled) from scala application via Azure Databricks cluster.

    I have uploaded my keystore.jks file to Databricks to path: /dbfs/streamsets/staging/presto_keystore.jks

    When I run task or a job which reads data from presto DB getting this exception  in Databricks cluster logs

    Seems that issue with reading SSL keystore.

    Can anyone please let me know steps to connect to presto DB via azure Databricks.

    and where should we place Keystore file in the cluster and how can we use it's path. We are using Run time databricks cluster

    with http connection (where no keystore file is not required) I am able to read data from presto DB via azure databricks.

    Thanks in Advance,

    Murthy
